Appiiearion fried Augiist s, 1914.v Serna No. 855,801.

. St. Louis, State ot' Missouri, ha\e inrented a new and useful Automatic lYater-Ileater,

K ol.E which the following is a specification.

'.l`hc present invention appcrtains to water heaters, and aims to provide a novel and impr-med boiler' vfor autonnitic gas water heaters.

A\ i'urther object oit this inrention is to provide a unique water circulating system, whereby the water will be quickly heated when the gas is turned on and the burner lighted by means o'l the pilot light.

YIt is also within the scope of the. present ii'iyention to improi'e generally, the construction ot the water heater, to enhance the utilitjv thereot, and to render the same co1nparatirely simple and inexpensive in construction, as well as practical, serviceable and eliicicnt in its use.

lVith the foregoing and other objects in riew which will appear as the description proceeds, the in\'ention resides in the combination and arrangement ot' parts and inthe details oit construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein Figure l is a vertical section oi the improved water heater, parts being shown in full. Fig. 2 is a plan View ot' the device. Fig. 3 is an enlarged sectional detail tal-:en on the line 3 3 of Fig. 1.

ln carrying ont the present invention, there is provide-d a peculiar water circulating system includingr an upright cylindrical water jacket 1 which has a water chamber 0r space between its inner and outer walls, and to the upper end of which is connected the cold water supply pipe Q. The supply pipe 2 is attached to the upper end of the. water jacket l in a peculiar manner, and to this end, a nipple 3 is engaged outwardly through the outer wall of the jacket 1, and is provided at its inner end with a flange or head 4 fitting snugly between the outer and eral branch or outlet 5, which is so directed within.thc jacket l, to create a rotar-V or whirling motion of the water withinl the jackct. y'l`he llai1ge""or head *l ol the nipple 2.5 litting snugly within the jacket, will close the inner end oil.'v the bore ot' the nipple, as seen in Figs. 1 and 2l, and it being eridcnt that the suppl)vv pipe 2 is threaded or otherwise engaged into the outer or lrce end of the nipple so that the water discharged l'roin the supply pipe 2 will pass intor thi nipple and laterally out the branch 5 into the water chamber or space within the jacket.

The water jacket l is prorided with a lower discharge or outlet including anipple (l, similar to the nipple 3, and engaged outwardl)Y through the outer wall ol" the jacket l. adjacent the lower end of the jacket, the nipple l haring a ilange or head 7 fitting snugly within the walls ot the jacket, and provided with a lateral or horizontal branch or inlet tv extending in a direction opposite to the direction in which the branch eX- tends, as indicated in F 23. Into the outer or tree end of the nipple (3, is threaded or engaged the lower end of a riser pipe 9, which extends upwardly on the exterior of the jacketr` and which has its upper end bent back within the upper end of the jacket 1, and attached to the upper end of a vertical coil 10 disposed within the jacket 1. A second vertical coil l1 is disposed within the coil 10, the lower ends of the coils 10 and 11 being connected, and a vertical elongated chamber 12 is disposed within the inner coil 1l, and the upper end oi`l the said inner coil is attaclnird to the upper end ot the chamber 12. Thus, when the water flows tl'irongh the jacket 1 into the riser pipe 9, it will flow downwardly within the. outer coil 10, thence uj'iwardly within the inner coil 11, and thence downwardly within the chamber 12, all ot which torni the water circulating systeni or conduits adapted to be heated by the burner, as hereinafter set forth.

A. discharge pipe 13 ltor the chamber 12, is attached to the lower end or bottom of the said chamber, and its outer end is attached to one end of a. casing ll haring an upstanding tubular discharge extension 15 which is provided at its upper or free end with an annular bevel 16.

A discharge chamber 17 is threadedly or inner walls of the jacket and having a latotherwise engaged over the upper or free end or' the extension 15, and is adapted 'for the connection ol the discharge pipe 18 which leads to the faucet or other point of discharge.

. The casing 14 is preferably disposed at one side of the lower end of the jacket 1, so that the extension 15 projects upwardly at one side of the jacket, it being understood that the several parts ot' the present apparatus may be supported upon any suitable stand, or inany other suitable manner.

The upper end of the water jacket 1 is provided with a damper, and to this end, a semicircular cover 19 is secured upon the upper end of the'jacket 1 to partially close the upper' end thereof, and providing convenient means for the passage of the upper end of the riser 9 into the upper end of the water jacket, as vseen in Fig. 1.

A semi-circular damper 21 is hinged to the cover 19, and is provided at its free portion with an extension or arm 22 for the engagement of the damper controlling rod or link, as will hereinafter appear.

The gas supply pipe 23,'which is preferably passed below the case 14, has its nozzle end communicating with the burner 211 which is disposed below the chamber 12 concentrically within the lower end of the water jacket 1. bly, although not necessarily, of the Bunsen Y type, and the nozzle or discharge end of the kgas supply pipe 23 projects upwardly within the Bunsen burner or mixing tube 21 whereby the air will bedrawn upwardly with the gas to provide the combustible mixture.

A controlling valve 25 is interposed in the gas supply pipe 23 adjacent the burner 24e, and is equipped with a controlling lever or arm 26. A pilot tube 27 is attached to the gas supply pipe 23 beyond the controlling valve 25, and extends to the mouth or discharge portion of the burner 24, to provide a pilot light for igniting the gas discharged from the burner 24, when the valve 25 is opened.

' As a means for automatically controlling the gas valve 25 and the damper 21, there is provided a rock shaft 28 journaled through one or both sides of the case 14 at a point remote from the extension 15, and having a lever or arm 29 secured thereto within the case 14E and projecting below the extension* 15. A stein or rod 30 which projects thrcugh the extension 15, is pivoted to the free end oit the lever 29, and is provided with a beveled piston or disk 31 adapted to move snugly within the upper portion of the extension 15 and to rise within the discharge chamber A17. The piston 31 is 'adapted to t a little loosely in the extension 1.5, to thereby enable a slight leakN age of the water from the extension 15 into The burner 24 is prefera` the enlarged discharge chamber 17 even when the piston is depressed. and to thereby avoid the sticking of the piston within the extension 15, which would be objectionable. The piston 31. is adapted to be lifted into the chamber 17 when the water is permitted. to discharge through the discharge pipe 18.

A lever or arm 82 is secured to the outer end or extremity of the rock shaft 2S, and a link 33 connects the free ends of the levers 32 and 26, whereby when the piston 31 is lifted into the chamber 17, as seen in Fig. l, the piston stem 30 will raise the lever 29, which will oseillate the rock shaft 28 and lever 32 carried thereby, to thereby raise the link 33 and the lever 2G to open the gas controlling valve Similarly, when there is no flow of water through the apparatus, the piston 31 will settle or gravitate into the extension 15, and the levers 29, 32 and 26 will drop or swing downwardly, to close the valve 25.

An upright rod or link 34; has its lower end pivoted to the free end of the lever 32, and has its upper end loosely engaged through the extension or arm 22 of the damper 21, as seen in Figs. 1 and 2, whereby when the lever 32 is raised and lowered, the damper 2l will be opened and closed, respectively.

In operation, the weight of the damper 21, damper rod 31, levers 29, 32 and 2G, links 33, piston 31 and piston stem 30, will cause the said parts to gravitate, when the llow of water through the apparatus is arrested, in order that the piston 31 will gravitate into the extension 15, and in order that the damper 21 and gas controlling valve E35 will both be closed when the apparatus'vis idle. Thus, the burner 2awill be extinguished and the damper 21 will be seated upon the upper end of the water jacket 1 to close the upperoutlet 2O of the water jacket. Now, when the water is turned on so as to liow through the discharge pipe 1S, the upward pressure of the water flowing from the extension 15 into the discharge chamber 17 will lift or raise the piston 31 into the chamber 17, and consequently. the lever 32 will be swung upwardly, to raise the lever 26 of the gas valve 25 and to raise the damper rod or link 34: to lift the damper 21. Consequently, the gas will be turned on into the burner 21, and will be ignited by the pilot light, and simultaneously, the damper 21 will be thrown open, to establish a draft through the water jacket 1 and to enable the products of combustion to pass ofi", after they have circulated through the coils 10 and 11 within the water acket 1 and around thc chamber 12. r1`he products oit' combustion being confined within the water jacket 1, will thoroughly heat the coils 10 and 11, and will also heat the water jacket 1 and chamber 12, to quickly heat the water as it lli nitraat? passes through the heater. As soon as the dow of water is shut on', the piston 3l will settle back to closed position within the eX- tension l5, and the damper 2l and Valve will be automatically closed, whereby the burnerfZ-t will be extinguished, and whereby the damper 2l will be closed, to retain the products of combustion within the water jacket l and whereby the subsequent heating of the water circulating system or conduits will be accelerated or rendered more quick, to alford economy in the consumption of gas or fuel.

lt is to be observed that the water in ,passing into the jacket l from the supply pipe 2, will be given its initial or primaryv bustion with the coils as the products of combustion rise within the water jacket l.. rlhe heated water will then pass into the chamber l2, where it will receive its final application of heat, it being noted that the chamber l2 will contain a sutlicient quantity of water, for ordinary domestic purposes for use at one time. An important feature resides in the provision of the peculiar nipples 3 and 6 for the inlet and outlet of the jacket l, whereby the water entering the jacket 1 through the nipple 3, will be given a rotary or whirling motion within the jacket, in connection with the nipple 6 at the lower end of the jacket which forms the discharge therefor. The whirling or rotary notion of the water is of advantage, inas- 4t` Milnuch as it Will carry the hotwater downwardly within the jacket, instead ofletting the hot water rise and accumulate at the upper end of the jacket, while the cold water would descend directly from the pipe 2 down one side of the water jacket to the riser 9. v

.From the foregoing, taken in connection with the drawings, the other advantages and attributes of the present apparatus will be obvious to those versed in. the art, 'without further comment being deemed necessary0 Having thus described the inyention, what is claimed as new is zl. ln a water heater, an upright water jacket having an inlet at its upper end, a coil disposed within the jacket, a riser connecting the lower end of the jacket and upper end of the said coil, a second coil disposed within the first mentioned coil, the lower ends of the coils being connected, and an upright elongated chamber disposed within the said second coil, the upper end of the second coil being connected to the upper end of the chamber, and the chamber having a lower outlet.

2. ln a water heater, a cylindrical water jacket, a water supply pipe connected to one end thereof and having alateral outlet with.- in the jacket, and an outlet connected to the other end of the jacket and having a lateral inlet within the jacket projecting in a direction opposite to the direction in which the said lateral outlet of the supply'pipe extends, so as to impart a whirling motion to the water flowingthrough the jacket.

3. In a water heater, a cylindrical water jacket, and nipples engaged to the jacket at its ends and having lateral branches within the jacket extending in opposite directions, so as to impart awhirling motion to the -water Howing through the jacket.

4. In a water heater, a cylindrical water jacket, and inlet and outlet nipples engaged through the outer wall of the jacket adjacent the ends thereof, the nipples having heads fitting snugly within the jacket and provided with lateral branches projecting in opposite directions, so as to impart a whirling motion to the water flowing through the jacket.V
